You can do it with String.split() but in this case it's simpler to use String.replace():
var description="Name:John;EmployeeID:2;Salary:$8000;Address:London";
description = description.replace(/;/g, '\n').replace(/:/g, ': ');
/*
"Name: John
EmployeeID: 2
Salary: $8000
Address: London"
*/

If you want the result as an object, try:
var f = function (str) {
var x = {}, key2label = { EmployeeID: 'Employee Id' };
str.replace(/(.+?):(.+?)(;|$)/g, function (match, key, value) {
key = key2label[key] || key;
x[key] = value;
});
return x;
};
If a simple string is needed, but you still need to replace keys:
var f2 = function (str) {
var key2label = { EmployeeID: 'Employee Id' };
return str.replace(/(.+?):(.+?)(;|$)/g, function (match, key, value, semi) {
key = key2label[key] || key;
return key + ': ' + value + (semi ? '\n' : '');
});
};
If you really didn't mean to replace keys, this will do it:
var f3 = function (str) {
return str.split(':').join(': ').split(';').join('\n');
};
... or use Matt Ball's answer.

With this statement:
var arrDescription = description.split(";");
you will get an array with all the values. For more info on split check the following link.
you can even join them afterwards :
printf(arrDescription.join(" "));
For more info on join check the following link.

how can i find a substring from arrDescription
JMax
@Saloni: are you trying to find an item in an array ? --> stackoverflow.com/questions/143847/… or stackoverflow.com/questions/237104/javascript-array-containsobj

i have only substring not the complete string
JMax
if i understand well, you want to do a search in your array with substring only. you could do a loop on your array but there might be a more efficient way so i advise you to ask another question so that javascript gurus will provide you with the best answers
You can probable try like this to display.
var description="Name:John;EmployeeID:2;Salary:$8000;Address:London";
var arr=new Array();
arr=description.split(";");
for(var i=0;i<arr.length;i++)
document.writeln("<h4>"+arr[i]+"</h4>");

if i have description in textBox then how can i use split function.
Srikanth Venkatesh
You can get the description from textBox using document.getElementById("textBoxId").value
Yes.
You first should split on the semicolon ;. Loop through those results, and split each result on each colon :.
You will have to build the result by hand.

var description="Name:John;EmployeeID:2;Salary:$8000;Address:London"; var splitted = description.split(";");
for(var i = 0; i < splitted.length; i++) { document.write(splitted[i] + ""); }
